Aaahhh polenta, it's never very good is it, what can you do with the stuff to raise it beyond bland shíteness?
Load it (and I do mean load it) with butter and parmesan, let it go cold, slice it and grill it.
You are right, though, that it is not big on inherent virtues. My fave chef, Alastair Little, on the subject:
Polenta is cornmeal porridge and to first tastes is about as attractive as it sounds (second and third tastes too). It has virtually no nutritive value, in fact people from poor polenta-eating areas, mainly in the Alps, suffered from various deficiency diseases due to their dependence on the stuff. Not only this, but it requires 45 minutes standing and stirring to cook - no wonder the diehards of the food world love it; it's tedious to prepare and tastes like grainy wallpaper paste. However, bowing to peer pressure, there are ways of making the stuff more than edible. Firstly, the Italians make it with with virtually no additions, a little butter and cheese perhaps, but they talk about the purity of taste and texture. These are precisely the qualities I strive to hide.
